Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
